BURNER.

vApplication filed September 10, 1924. Serial No. 736.959.

My present invention has reference to a hydrocarbon burner and has for its object to produce a burner construction in which the fia-me from the burner is surrounded by and has miXed therewith a desired quantity of air to insure a perfect combustion of the fuel.

To the attainment of the foregoing, ref erence is to be had to the drawings which accompany and which form part of this application.

In the drawings:

Figure 1 is a substantially central vertical longitudinal sectional view through my improvement.

Figure 2 is a sectional view on the line 2-2 of Figure 1.

Figure 3 is a bottom plan view.

As shown by the drawings, I make use of a base 1 which is in the nature of a casting and which is round in plan. The base has a peripheral downwardly extending flange and is centrally provided on its upper face with an annular enlargement in the nature of a boss 2. The boss 2 on its upper flat face is centrally formed with a nose extension 3 that has a threaded opening therethrough aligning with a similar open ing in the base. The boss 2 is provided with an annular series of openings -1 that surround the nose 3.

The boss 2 is arranged centrally within an annular rib 5 formed on the said upper face of the base. This rib has oppositely disposed lateral extensions 6 that terminate in upwardly extending short pipe sections 7, there being a shoulder 8 provided by the rib 5 that partly surrounds the said pipe members 7.

Screwed through the referred to opening in the boss 3 and base 1 there is a fuel conducting pipe 9, and screwed on the upper and threaded end of the pipe there is a pan 10. The panV is round in plan, having a peripheral upstanding flange 11, and an inner' liange 12, the latter at spaced intervals being notched, as at 13. The pipe 9 is screwed in an opening surrounde-d by a boss 14 on the outer face of the pan, the said boss being provided with an opening that registers with the bore of the pipe 9. The flange 12 partly retards the-flow of the liquid fuel delivered into the pan but a determined quantity of such fuel will pass through the notches 13 and be retarded by the peripherv15 is employed. The ends of the branches of this con-duit rest on the short .pipes 7. The inner portions of said ends are surrounded by substantially semi-cylindrical depending iianges 16 which rest on the shoulders 8. rlhe conduit has its inner face centrally formed with an opening 17 that is preferably surrounded by a depending flange 18. The opening is flared outwardly toward the bore of the conduit.

As previously stated, air passes through the openings 4; and likewise through the pipe sections and the conduit 15 and is thus directed downwardly and wholly around the pan 10 so that a proper quantity of air will be fed to the burner to mix with thc liquid fuel therein. The improvement is primarily designed for use in heating furnaces but is not necessarily restricted to this employment. Because of the arched formation of the conduit 15 a flame may be readily applied to the fuel in the pan of the burner, and the passage of the fuel through the pipe 9 is, of course, controlled by a valve not shown.

Having described the invention, I claim A hydrocarbon burner comprising a flat base which is round in plan and which has a peripheral -depending flange, a boss centrally formed on the base having a central nose projection, a fuel conducting pipe screwed through the base and nose, said boss having openings surrounding` the nose, a fuel pan screwed on the outer end of the pipe and communicating with the bore thereof, said pan having peripheral and intermediate flanges, the latter being notched,

an annulaiii'ib on the topof the base having lateral branches terminating in npstanding short pipe sections, an ai'ohed air conductor pipe having its ends resting on said short pipes and having semi-circular anges resting on the shoulders provided by zthe lateral extensions of the rib', and said ail' conductor pipes having its inner Wall formed With an outwardly flared opening disposed centrally above the pan, and a flange surrounding said opening.
